It will 1) establish a registry of patients with cerebrovascular disease (stroke); 2) characterize the natural history of acute stroke and transient ischemic attacks (TIA)-an interruption of blood flow to the brain that causes stroke symptoms for a short period of time); and 3) evaluate the data to generate ideas for future studies.\n\nPatients 18 years of age or older with suspected acute stroke or TIA may be eligible for this study. Subjects will be recruited from patients who present with stroke at the emergency department of Suburban Hospital in Bethesda, Maryland.\n\nThe study will gather data collected from diagnostic and laboratory tests the patient undergoes as part of standard medical care, including findings of medical and neurological examinations and other tests. In addition, studies will be done for research purposes only to gather data about stroke and TIA. These may include the following:\n\n* Blood and urine tests not more than 2 tablespoons of blood will be drawn for various tests.\n* Electrocardiogram (EKG) (heart tracing)-electrodes placed on the chest wall detect the heartbeat and heart rhythm.\n* Computed tomography (CT) scan of the head-specialized X-rays are used to obtain images of the brain.\n* Magnetic resonance imaging (MRI) of the brain-a strong magnetic field and radio waves are used to produce images that provide information about the brain tissue and blood vessels.\n* Transcranial Doppler (TCD)-sound waves are used to image the arteries of the brain and neck.\n* Echocardiogram-sound waves are used to image the heart and evaluate heart function.\n\nPatients may be asked to return to Suburban Hospital for follow-up testing in 1, 3, and\u002For 12 months, when some of these tests may be repeated to assess changes over time",[25,26,27,28,29],"Brain Disease","Ischemic Attack, Transient","Cerebrovascular Accident","Cerebrovascular Disorder","Vascular Diseases",[31,32,33,34,35,36],"Stroke","Natural History","MRI (Magnetic Resonance Imaging)","Magnetic Resonance Imaging","Acute Stroke","TIA","RECRUITING","2026-06-13",{"date":40,"type":41},"2026-06-16","ACTUAL",{"date":43,"type":41},"2001-01-26",{"name":45,"class":46},"National Institute of Neurological Disorders and Stroke (NINDS)","NIH",3,{"id":49,"slug":50,"hasResults":11,"nctId":51,"briefTitle":52,"officialTitle":53,"acronym":54,"eligibilityCriteria":55,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":56,"enrollmentInfo":57,"targetDuration":4,"studyType":59,"phases":60,"briefSummary":62,"conditions":63,"keywords":4,"overallStatus":37,"whyStopped":4,"lastUpdateSubmitDate":64,"lastUpdatePostDateStruct":65,"startDateStruct":67,"completionDateStruct":69,"leadSponsor":71,"locationsCount":5},"100259926","performing-a-low-dose-whole-body-angiography-as-the-first-element-of-an-imaging-assessment-following-stroke--tia-100259926","NCT02662751","Performing a Low-dose, Whole-body Angiography as the First Element of an Imaging Assessment Following Stroke \u002F TIA","The Impact of Performing a Low-dose, Whole-body Angiography as the First Element of an Imaging Assessment Following Stroke or Transient Ischemic Attack in Comparison With Usual Care: a Randomized, Controlled, Open Trial","VASCU","Inclusion Criteria:\n\n* The patient was informed about the implementation of the study, its objectives, constraints and patient rights\n* The patient has given free and informed consent and signed the consent\n* Patient affiliated with or beneficiary of a health insurance plan\n* Patient available for 36 months of follow-up\n* The patient has had a stroke (within the past 10 days, diagnosis confirmed by MRI with a diffusion sequence) or transient ischemic attack (within the past 10 days, ABCD2 score greater than 3) without haemorrhage\n\nExclusion Criteria:\n\n* The patient is currently participating in or has participated in another biomedical research study within the past three months or is currently in an exclusion period determined by a previous study.\n* Patient under guardianship or judicial protection\n* Refusal to sign the consent\n* Inability to correctly inform the patient or his\u002Fher trusted person about the study\n* The patient is pregnant, parturient, or breastfeeding\n* The patient has a contraindication for a treatment used in this study\n* Known allergy to contrast medium or severe allergy to iodine\n* Known active malignancy or history of cancer treatment\n* The patient has already undergone a full body scanner in the previous three months\n* Renal failure with creatinine clearance below 60 ml \u002F min\n* Monoclonal immunoglobulin\n* History of severe symptomatic cardiovascular event (myocardial infarction, aortic dissection, mesenteric ischemia, renal ischemia)\n* Emergency situations that hamper the planned course of the study","89 Years",{"count":58,"type":21},260,"INTERVENTIONAL",[61],"NA","The main objective of this study is to compare two post-stroke\u002FTIA (transient ischemic attack) imaging strategies in terms of the number of clinically important (i.e. requiring specific treatment according to current recommendations) lesions detected.
